Abstract: A display apparatus includes a display module, a first supporting portion, a second supporting portion, and a reinforcing member. A folding region, a first non-folding region and a second non-folding region are defined in the display module, when viewed in a plan view. The display module displays an image. The folding region is foldable about an imaginary folding axis, and the first and second non-folding regions are adjacent to two opposite sides, respectively, of the folding region, respectively. The first supporting portion supports the first non-folding region. The second supporting portion supports the second non-folding region and is spaced apart from the first supporting portion. The reinforcing member is adhered to the first and second supporting portions. The reinforcing member includes an incision pattern, which overlaps the folding axis in the folding region.
